Two ways you could evaluate 37% of the sum of \(27 \frac{3}{5}\) and 15.9:

1. Convert the mixed number \(27 \frac{3}{5}\) to an improper fraction or a decimal, then add it to 15.9. Multiply the resulting sum by 0.37 to find 37% of the total.

2. First calculate 37% of each number individually: find 37% of \(27 \frac{3}{5}\) and 37% of 15.9 separately. Then, add the two results to get the final answer.

Answer (2)

First way is to first find the sum and then find 37% of it. Second way is another way round, find 37 of 27 3/5 and 37% of 15.9 and then add it.
Lets do it 37%=0.37 0.37 ∗ ( 27 5 3 ​ + 15.9 ) = 0.37 ∗ ( 43.5 ) = 16.095 - its the result Second way its 0.37* 27 3/5 + 0.37*15.9=10.212 + 5.888=16.095

You can evaluate 37% of the sum by first adding 27 5 3 ​ and 15.9, then finding 37% of the total. Alternatively, calculate 37% of each number separately and then add the results together. Both methods yield the same result of 16.095 .
